Sun ld can be better on Solaris than GNU ld for C programs.

You should always use GNU ld with g++ for C++ programs though. The GNU
toolchain and the Solaris toolchain have different ideas on how to
implement templates and if you mix & match you can end up with huge
libraries and executables due to duplication of templates.

Are you sure it was using GNU ld? You generally have to recompile gcc to
tell it which linker to use (there's a --with-gnu-ld option to
configure). It usually hardcodes the location of the linker and doesn't
rely on your path. There's a --print-somethingorother option you can
give to gcc to get it to report what it will use.
